It seems my questions were overlooked but I found my answers.
For anyone else that is curious about the time to seroconvert and show a positive result after the onset of symptoms from a primary result, you can view the study below:
Quest uses HerpeSelect IgG ELISA for testing.
Per Quest: The median interval between symptom onset and IgG seroconversion (for HSV-2) was 21 days for the HerpeSelect ELISA.
Reading the linked study and associated figures, the time it takes to see a positive HSV-2 IgG test result after onset of symptoms for a primary outbreak:
50% seroconvert by 21 days
77% by ~42 days (6 weeks)
93% by ~90 days (3 months)
At the time of my test I was just over 21 days after potential symptom onset so the test results aren’t very meaningful. However, it did rule out prior infection and isolated the partner so it was useful for that purpose.
Anecdotally, it seems most classic lesions resolve relatively quickly (around 1-2 weeks) but I found some (subsequently confirmed) examples of the lesions lasting longer before healing.
One other question: How long do the lesions typically last? From the anecdotal information I have read they seem to progress and change quickly for many people (appearing and resolving over the course of a week).
Is it unusual for a lesion to last 3-4 weeks, even if it is the first OB?
